ABSTRACT:
An apparatus and method for removing liquid from liquid bearing material is provided, the apparatus comprising a pair of spaced apart electroes for being disposed on opposite sides of the material, a unit for creating an electrostatic field between the electrodes for acting through the material to remove liquid from the material, a plurality of projections for being disposed in the material between the electrodes to assist in removing liquid from the liquid bearing material, one of the electrodes having a plurality of openings passing therethrough for respectively receciving the projections therethrough so that the projections can project into the material between the electrodes, a unit operatively interconnected to the projections to move the projections through the opening means of that one electrode to different positions thereof relative to the material between the electrodes and relative to the one electrode, and a unit for causing at least one of the projections to create an electrostatic field with another of the projections so that that electrostatic field extends between those two projections and through the material to act thereon.
